Description

The Invention relates to a hand-held device, with the help of which on a roll befindliches, tape from a in particular one-sided adhesive-coated carrier, the adhesive with a release material is covered, can be unrolled, and indeed in particular adhesive tapes, the splice required in the paper and printing industry to connect two paper rolls.

The paper industry uses water-soluble adhesive tapes such as the tesa ^® 51447. This adhesive tape is a one-sided adhesive product. This is used for splicing applications. Due to the properties of carrier and adhesive as water-soluble, repulpable product, which can also be printed, the carrier must not be provided with a backside coating. In order to still be able to wrap the product to the roll, the adhesive is covered with a siliconized release paper. This cover must be removed before bonding.

The Bonding for splice preparation is done manually today. Because of the size of the paper bales (these are up to ten meters wide) on which the bonding is performed, is the handling during the bonding by the previously deducted release paper very difficult.

This is the reason that the desire for a simple but effective application device emerged is.

At the Market available dispensers are not for different reasons suitable. Simple handsets for one-sided Adhesive products are unsuitable as the release paper is damaged by these Devices not can be deducted.

The known hand-held devices for double-sided adhesive Products are also not suitable, because here too the transport system of the adhesive tape by the hand-held device always based on an adhesive side, because usually are double-sided Adhesive products not covered by on both sides. In addition, will in all commercial Dispensing the release paper from the top of the double-sided Duct tape peeled off and the lower, uncovered adhesive side will be at the same time for used the correct transport within the device.

The most handsets Beyond that for the application as far too big and Too heavy, so considered too unwieldy. This is because of the very long bond line on which the tape must be glued and which must be absolutely straight and wrinkle-free. The processors are used to glue only short distances piece by piece in order to do so To be able to correct direction again and again. This is allowed through the hand dispenser not be complicated.

Just as an example, a dispenser is mentioned, as in the DE 299 14 317 U is disclosed. This serves for unrolling on a roll befindlichem, preferably one-sided self-adhesive equipped material and consists of a handle, a movably mounted on the handle holder, wherein on the holder a rotatably mounted pivot pin for receiving the roller is present. The roller has a freedom of movement in the axial direction.

Of the Holder is held in position by a spring in particular, that the roller located on the pivot against a also on grip attached leadership role is pressed being the leader laterally protruding guides having. The leadership is particularly effective in the case when the laterally projecting guides bevelled inwards are.

At the actual dispensing process is the material from the roll over the leadership led to a donation is used, by means of which the material is placed on the ground.

This Dispenser is used when painting surfaces - especially motor vehicles - if sharp paint edges desired become. For example, in a transition from a paint to a others, or at a transition from a surface to be painted to a not to be painted, as he among other things at only one Part to be painted bumper made of plastic is present.

Around To ensure this lacquer edge, today adhesive tapes are on the surface to be painted applied, so-called "fineline tapes." These tapes are thereby glued on the ground, that their one lateral Edge adjusts itself after painting resulting paint edge.

task The invention is to provide a handset that is at a very simple design, small, light and easy to donate an adhesive tape of a particular one-sided adhesive-equipped carrier whose Adhesive composition is covered with a release material, is suitable for which the release material is removed from the adhesive of the adhesive tape during dispensing must become.

Is solved this task by a handheld device, as set forth in claim 1. Further developments of the hand-held device according to the invention are thereby Subject of the dependent claims.
